I believe you are correct - using a digital ballast in conjunction with a Uninterruptable Power Supply (like a big honkin APC unit) is fundamentally the same as when a PC is hooked up to one. For a 1k Watt HID setup, it would have to be a good UPS though.

Makes me ponder going after some used server-room grade batteries....hrmmm
BlueDevil Reviewed by BlueDevil on . Growers using multiple HID lights I have a question for some of you growers using multiple 1000w HID lights. If you could do it all over agian and rebuy lights- would you stick with your 1000w or switch it up to 600w?? im thinking of switching to 600's, that is why I ask. thanks for any input!! Rating: 5
